OTHER SG-2100 Motor Bracket Wanted

[cyberham]

I know this is a real shot in the dark....but I'm looking for anybody who may have an old SG-2100 motor with mounting bracket/bolts that aren't too rusted out like mine. My actual motor still works fine after 12+ years, but the bracket scales and bolts are rusted almost to the extent that they can't be used. Below is what I need.

What mine looks like...

Does anybody have these?

In the absence of new old stock parts, I would treat, prime, and paint the brackets and replace the square U bolts with straight bolts. For the pivot and scale bolts, I would just thread-match and add some flat and lock washers as required to compensate for missing material. Run to outright failure.

Alternatively, if you believe that motors will become more expensive and challenging to source due to a limited North American market, consider buying a new device and paint the surfaces before performing (preferably) a one-and-done installation.

Everyone else's mileage may vary.

I agree that improving the motor I have is better than buying a whole new motor. Though I see a new SG-2100 is available from New York City for about CDN$225 delivered.

If I can clean off the rust from the existing bracket so I can read the scales, then replace the four bolts with identical new ones, this would help a lot. One bolt has rounded edges due to use. Finding new bolts with identical threads might be tough near where I live. The square U-brackets are fine as they are if I just get new nuts and lock/flat washers for them.

I will consider all of this next time I take the motor out of the system. It's working fine for all receivable satellites now so I won't touch.

For the scale position, I would mark the elevation first with a pen then use a punch to mark both sides of the track, then it matter less if your values disintegrate due to mother nature or if you paint over them.

As for the fasteners, my inclination is that the motor assembly is from Asia and likely uses commodity metric bolts, rather than SAE, with a typical pitch. I cannot see the OEM going out of their way to tool up for anything custom. I would start with the idea of a regular M8x10 or M8x15 specification and go from there. You might consider calling Fastenal in Nanaimo or Gibsons Fasteners in Gibsons to see what they have on hand and bring the assembly into the store to specifically test the fitment. I would also buy a few extra to facilitate long-term maintenance. The incremental cost is minor when compared to the aggregate value of the hassle and of your time.

Everyone else's mileage may vary.

I think this motor was made in Taiwan. I can take a sample of the bolts with me to my local store and see what they have. I definitely would buy a few extra if I find the right ones. Locally, we have Rona, Home Hardware, Canadian Tire and a building supplies store. I can do the same for the nuts and washers.

As for taking the motor to a store, that would have to wait until I dismantle the installation for some reason. It's working too well after my work yesterday to disturb it now. I'm receiving everything from 129W to 82W with good SQ as it is (even in the pouring rain). Beyond that, I can use my other 41" dish to play with outside that range.

I would go to those stores in the order you have listed. The Rona website suggests they have some M8 options already in the store. Pick up some rust converter while you're there.

Evapo-Rust hands down. I wasn't a believer until I saw it used and tried it. The degree scale might just reappear without any abrasives. Black etching primer afterwards followed by a few coats of rattlecan-du-jour.
Everything now in the USA is metric. A good hardware store, Fastenall, Mom and Pop full feature hardware store will be able to hook you up.

I see Evapo-Rust online and it sounds good. But it doesn't pop up when I check my local stores online. They do have many other rust dissolvers. I already have a Blaster product which worked wonders previously to loosen corroded bolts.

Didn't know you spoke French.
